Greubel ForseyThis Greubel Forsey GMT Sport Earth wristwatch features an ovoid titanium case measuring 45 mm in diameter fitted to an integrated blue rubber strap. The three-dimensional openworked dial showcases an inclined 24-second tourbillon positioned at 1 o'clock, alongside a power reserve indicator at 4 o'clock and a rotating three-dimensional globe displaying universal time from a North Pole perspective at 7 o'clock.
A combined subsidiary dial between 10 and 11 o'clock indicates running seconds and a second time zone via a red hand. Driven by a manual-winding movement, the timepiece incorporates pronounced central arch bridges and an engraved titanium bezel with the brand's core philosophical tenets.

- Documentation and Source Limitations
- The case back is described in the source essay as featuring a sapphire cities disc displaying UTC universal and summer time across 24 cities; however, the reverse of the case is not visible in the provided image and is not independently verified. The source documents exhibit an internal discrepancy regarding the edition size: the auction listing states that the Certificate of Authenticity confirms a '1/1 status', while the cataloguer's essay describes the watch as a 'unique piece 1/11'.
- Dial Display and Movement Architecture
- The openworked three-dimensional dial features skeletonized central hands with luminous triangular arrow tips extending over an arched bridge structure. A suspended arch center bridge supports the gear train driving the hours and minutes hands. At 1 o'clock, the inclined tourbillon completes a full rotation every 24 seconds, with a cage reported in the essay to consist of 88 components weighing 0.38 grams. Universal time is tracked at 7 o'clock by a three-dimensional blue and silver-tone globe visible from above the North Pole, turning in real time and surrounded by a sapphire crystal ring with 24-hour day/night divisions. An auxiliary dial between 10 and 11 o'clock integrates running small seconds on a rotating disc with a second time zone hand, alongside a power reserve indicator at 4 o'clock.
